Walk in natural park along the granite etc Serralada de Marina coastal range just north of Barcelona. Sporadically improved early C20th town centre. Gipsies and wild people (seasonal). Mental hospital, ruined chapels, C14th-16th monastery (1/2/3/4/5/6 visits bookable). Classic Mediterranean flora: lots of pine (umbrella,stone), chunks of Quercus ilex, standard array of flowers, cacti. (Optional: hidden spring with mutton-mad pussy (blog); scrabble up hill to escape hippies.) Historically interesting triangulation point. Excellent views over Sant Adrià (1/2/3; blog), Montcada cement factory & Collserola, Barcelona/Montjuic, Montseny. C18th-19th hamlet with good cemetery (1/2/3) and farms. Optional drinks in (and stroll around) rather nice village centre; optional museum visit (ask!). Modernist villas supersede farms and make way in turn for spraycan 70s. Ruined fort (blame the French and the railway company). Bars/beach/chimney.
